Lol, I used to work in those a few years back, mighty impressive. My first day at work there was a pea souper and I had to ask a postie where they were, he laughed and said but for the fog you'd have seen them from ten miles away!!! He wasn't wrong! Got the security guard to unlock the dodgey stairs one evening when e eryone had gone home and climbed all the way to the apex, vertigo or what!!! There's a tiny window at the top and you can see for miles. Just thought I'd share that with you
